"I myself posses DNA samples that are possibly collected from a Bigfoot but since I didn't actually see the creature leave the sample, it is still an unknown and therefore unworthy of testing at this time."
So Chris, lets pretend that on one of your research trips, you come across a big, hairy, human-like foot caught in an old forgotten bear trap. Bingo - this is the body part you claim to be looking for. You have stated often that even though you are NO-KILL, only a body part of full body will do. Based on the reasons you are using to not get the saliva tested, you can't get the body part tested either...you didn't see the bigfoot leave it for sure. In fact, that argument pretty much holds for anything you find, doesn't it?
The only thing you are doing by refusing to do something with the saliva and the HD video from 15 ft away is prove that you are just BLAARGing. BTW - the saliva is equivalent to a body part - it has the ability to "prove" the same thing that a bloody foot would.
I'll eat a whole appetizer platter full of bugs and a main course of crow if you show us to be wrong and bigfoot exists.
You are worried about your info getting out, just use your NDA...no problem, right?
